| چکیده | ||
| به منظور بررسی تأثیر نیتروژن و زمان های مختلف برداشت بر عملکرد سورگوم، آزمایشی در سال 1389 به صورت کرت های خرد شده در قالب طرح پایه بلوک های کامل تصادفی با سه تکرار در مزرعه تحقیقاتی دانشگاه آزاد اسلامی واحد اردبیل انجام شد. فاکتورها شامل سطوح مختلف کود نیتروژن از منبع اوره در چهار سطح (صفر، 60، 120 و 180 کیلوگرم در هکتار) و زمان های مختلف برداشت علوفه در سه سطح شروع گلدهی، دو و چهار هفته بعد از گلدهی بودند. نتایج نشان دادند که بیشترین عملکرد علوفه در کرت هایی براورد گردید که 180 کیلوگرم کود نیتروژن در چهار هفته بعد از گلدهی استفاده شده بود و کمترین آن در حالت شروع گلدهی و بدون مصرف کود نیتروژن براورد گردید. مقایسه میانگین ها نشان داد که بیشترین میزان کارایی مصرف کود در به کارگیری 60 کیلوگرم کود نیتروژن در چهار هفته بعد از گلدهی و کمترین مقدار آن در حالت شروع گلدهی با مصرف 180 کیلوگرم کود نیتروژن براورد گردید. بیشترین مقدار پروتئین ساقه و برگ در بالاترین مقادیر از مصرف کود نیتروژنه براورد گردید. با توجه به نتایج پژوهش حاضر، به منظور افزایش عملکرد علوفه سورگوم در شرایط اقلیمی منطقه مورد بررسی، توصیه می شود برداشت در مرحله چهار هفته بعد از شروع گلدهی با مصرف 180 کیلوگرم نیتروژن در هکتار انجام شود، اما چنانکه بهبود کارایی مصرف کود مدنظر باشد، 60 کیلوگرم نیتروژن در چهار هفته بعد از گلدهی پیشنهاد می گردد. | ||

| چکیده [English] | ||
| In order to study the influence of nitrogen and different harvesting dates on sorghum yield, a split plot experiment based on randomized complete block design was conducted with three replications in 2010 at the Research Farm of Islamic Azad University, Ardabil branch. Factors were: different harvesting dates in three levels containing, beginning of flowering, two and four weeks after beginning of flowering and nitrogen fertilizer in four levels (zero, 60, 120 and 180 kg N.ha-1). The results showed that maximum of forage yield was obtained by the plots which were applied 180 kg N.ha-1 in four weeks after beginning flowering and the least of it was in no application of nitrogen fertilizer in beginning of flowering. Means comparison showed that the highest nitrogen use efficiency was obtained by the plots which was applied 60 kg N.ha-1 in four weeks after beginning flowering and the least of it was in application of 180 kg N.ha-1 × beginninig of flowering. Maximum of stem and leaf protein was obtained in the highest of nitrogen fertilizer rates. It seems that in order to increasing of forage yield, should be applied 180 kg N.ha-1 × four weeks after beginning flowering in climate conditions of Ardabil. If the aim is to improve nitrogen use efficiency, then applying 60 kg N.ha-1 in four weeks after beginning flowering can be suggested. | ||
